| This study evaluates the economic impact of a ban on methyl bromide on the U.S. winter fresh vegetable market for six major crops: tomatoes, green peppers, cucumbers, squash, eggplant, and watermelons. Florida is the primary domestic supplier of these products. Mexico and Texas are the competing suppliers of the five vegetable crops and peppers, respectively. Leontief technologies represent both monocrop and double-crop production systems; linear inverse demand functions represent four demand regions in the U.S. and Canada. By increasing production costs and reducing yields, a ban on methyl bromide decreases Florida's FOB revenues by 54% and increases those of Mexico by 65%. Price increases to U.S. fresh vegetable consumers range from near zero to over... |

| An analysis of a typical crop and livestock farm in North Florida is presented. The analysis incorporates the potential competition and complementarity among crop and beef cattle enterprises. A Target MOTAD model is developed to account for risk in a decision framework. The results indicate that when income risk is ignored, peanuts, watermelon, and stocker cattle are the only enterprises included in the optimal solution. When income risk is heavily weighted, the optimal solution includes peanuts, watermelon, stocker cattle, cow-calf, and irrigated soybeans. The results suggest that the persistence of cow-calf production may be explained as a stabilizer of income. |

| A demand model is developed to examine the impacts on orange juice prices resulting from elimination or reduction of the tariffs on orange juice imposed by the United States, European Union, and Japan. An empirical analysis suggests that elimination of the U.S. tariff by itself would decrease the U.S. orange juice price by about $0.22 per gallon, while simultaneous elimination of the U.S., European, and Japanese tariffs would decrease the U.S. price by about $0.13 per gallon. Alternatively, reducing these tariffs according to the Swiss 25 formula would decrease the U.S. price by an estimated $0.09 per gallon. The U.S. produces about 1.4 billion gallons of orange juice annually and each penny reduction in the price impact increases U.S. orange juice FOB... |

| This study considers the allocation of Florida citrus‐grower money between advertising and research programs to maximize grower revenue net of program costs. The allocation depends on the impact of advertising on demand and the impacts of research on the cost of production and supply. A number of studies have estimated the impact of advertising on OJ demand, but little is known about the impact of research. Research on citrus greening, a disease that has no known cure, is examined in the present study. There are no past studies to reliably gauge the impact of this research. The approach taken here is to ask if a given amount of research dollars is needed to reduce average production costs by certain amount, then what should be spent on advertising based on... |

| The use of alternative probability density functions to specify risk in farm programming models is explored and compared to a traditional specification using historical data. A method is described that compares risk efficient crop mixes using stochastic dominance techniques to examine impacts of different risk specifications on farm plans. Results indicate that a traditional method using historical farm data is as efficient for risk averse producers as two other methods of incorporating risk in farm programming models when evaluated using second degree stochastic dominance. Stochastic dominance with respect to a function further discriminates among the distributions, indicating that a density function based on the historic forecasting accuracy of the... |

| Florida is typical of many southeastern states in that it exports feeder cattle and imports carcass and boxed beef. The objective of this paper is to estimate the cost of retaining feeder cattle in Florida, feeding these cattle to slaughter weights, slaughtering them, and distributing the meat to retail outlets. A mixed integer programming model is developed. The optimal number and location of feedlots and slaughter plants are determined. The results indicate that at production levels exceeding 600,000 head, the cost of producing carcass beef in the State is comparable to the average for the United States. |

| Supermarket shelves are saturated with numerous varieties and brands of juice beverages. This high level of assortment has dramatically changed beverage consumption patterns and trends throughout the United States. In fact, during 2004-2005, energy and sport drinks experienced significant increases in sales, 65.9% and 20.6 %, respectively. During the same period of time, refrigerated juice sales increased a mere 2.2%, shelved non-fruit drinks decreased 0.9%, bottled juices and cocktails both decreased 1.5 % and frozen juice decreased by 12.8% (Food Industry Review 2006). The beverage industry has undergone many transformations, but consumer theory states that a shift in demand for one good has to be compensated by a shift in the opposite directions in the... |
